The network robustness against cascades is crucial for many networked systems. In the paper, we enhance the network robustness against cascades by rewiring edges of networks. Three edge-rewiring strategies are compared, including random rewiring strategy (RRS), assortative rewiring strategy (ARS), and low-polarization rewiring strategy (LPRS). The results show that ARS is more effective than RRS to...
Motivated by recent developments in the theory of complex networks, we examine the tolerance of communication networks for intentional attacks that aim to crash the network by taking down network hubs. In addition to providing a brief survey of key existing results, we investigate two different effects that largely have been ignored in past studies. Many communication networks, such as the Internet,...
